For a vertical blade and motor setup, how much torque would be required to slice an average sized carrot?
Homework Answers
generally based on data on internet energy required to cut an carrot will be nearly equal to 4.55 joules ...
we know that torque x angular velocity = power
so based on the angular velocity of the velical blade the toque depends ... generally if we take angular velocity as as 6.67 (motor of 60 rpm) we get 4.55/6.67 = 0.6821 Nm torque .....it always varies with angular velocity

An electric saw uses a circular spinning blade to slice through wood. When you start the saw, the motor needs 5.00 seconds of constant angular acceleration to bring the blade to its full angular velocity. If you change the blade so that the rotating portion of the saw now has 2.00 times its original rotational mass, how long will the motor need to bring the blade to its full angular velocity? Answer: T2 =? seconds

For the materials handling mechanism described in Problem, determine the torque required from the motor if the motor is rotating at 120 rpm and decelerating at a rate of 100 rad/s2. The materials handling mechanism, shown in Figure, slides 4 kg packages along a counter. The machine operates with the crank rotating counterclockwise at a constant rate of 120 rpm. The coefficient of kinetic friction between the package and counter is 0.15. The weight of all the mechanism links is...

Let us treat a helicopter rotor blade as a long thin rod, as shown in the figure. (Figure 1) . If each of the three rotor helicopter blades is 3.75 m long and has a mass of 135 kg, calculate the moment of inertia of the three rotor blades about the axis of rotation. b- How much torque must the motor apply to bring the blades from rest up to a speed of 5.9 rev/s in 10 s ?
